Picture of Making 'Glove One' - a 3D-printed, wearable cell phone.
Hello!  I'm Bryan Cera, and I love to make weird stuff out of electronics! It is my passion. For this instructable, I'd like to take you through my process of creating Glove One, a functional cell phone that you wear on your hand. I've made a few tutorials in the past, but this is my first official instructable.  I see it as my first attempt at giving something back to the online communities of makers I've been learning from.

Any of the processes involved in this instructable can easily be applied to any project in the realm of hacked electronics, DIY hardware, or digital fabrication. That said, I hope you enjoy: Making Glove One.

Step 1: Preparation

Picture of Preparation
There are two different ways one could attack this project.  You could start from scratch, like I did, or you could work from the cad files I've made freely available here.  I created a parametric design for the finger segments, so they are pretty easy to modify to fit different hands - see the 'Drawing the virtual model' step for more info on that.

If you choose to start from scratch, I'd imagine the entire build would take about two months (not including delivery times for components or outsourced parts).  That's of course assuming you already have a bit of experience with a CAD program and know your way around a soldering iron.

If you start from my cad drawings, you could easily bang out your own Glove One in less than a month.

That said, I will start this tutorial by laying out all of the materials and tools I used for the build, and provide links where I can.

Materials used for the project:

- masking tape
- electrical tape
- shrink tubing
- surface-mount tactile switches (KSR251G)
- custom 3D print from Ponoko (see 'Step 6: Digital Fabrication')
- sheet metal components cut by Ponoko (if you don't cut your own)
- micro nuts and bolts (from microfasteners.com)
- extension springs    (from Small Parts on Amazon)
- a used or new cell phone (I used Burg Watch Phone "Midnight Black")
- zap-a-gap epoxy (on Amazon)
- plastic-bond spray paint (I used 'Fusion for Plastic' by Krylon)
- plasti-dip (from Plasti-Dip on Amazon)
- 3in x 3in x .06in PETG Sheet Plastic (I used scraps, but can find on Amazon or Midland Plastics)
- 3in x 3in x .06in Acrylic Sheet Plastic (I used an old scrap, but can find on Amazon or Midland Plastics)
- .5in x .5in copper foil OR copper foil tape (on Amazon)

Tools Required for the project:

- digital camera OR scanner
- soldering iron
- tweezers
- small screwdriver
- exacto knife
- 600, 600, and 1200 grit wet-or-dry sandpaper
- heat gun

Other useful (but not required) materials/tools for the project:

- card stock or manilla folders
- several short wooden dowels
- reusable poster adhesive
- de-soldering wick
- all-purpose cleaning agent
- metal files and/or sanding sticks
- dremel tool
- vinyl plotter (I bought a Vinyl Express for only $250 and it has come in handy for tons of projects!)
- 8in x 10in x .02in sheet aluminum (if you plan to cut your own metal components - from Small Parts on Amazon)
- CnC mill (if you plan to cut your own metal components - I used a friend's Taig Desktop CnC Mill)

Before we get started, I'd just like to mention that as this project involves chemicals and potentially dangerous tools, it is important to take appropriate safety measures (i.e. rubber gloves, respirators, safety glasses.) I'm safe. I'm set.

I've gotten several requests for more information on how much it would cost to build one's own Glove One. I decided to address this on my blog... check out the post here:


I'd love to see pictures of people's Glove One builds.  Send em my way, and if it's okay with you, I'll feature them on my website!

Happy making!
can other people call us ?

Yeah, it's a fully functioning phone.
thanks awsome
can we also use a dremel to smothen the glove
Bryan Cera (author)  babu14233 years ago
I doubt a dremel would be necessary... nothing needs any extreme modification.

Several sheets of fine-grit sandpaper should do the trick. Sanding sticks can help get into the hard-to-reach areas of the printed components:

you can use flexsometer

What kind of plastic is used in the glove itself and what is the thickness of the tabs with the pegs that you used to snap the fingers together?

Looks like the hand of a call of duty advanced warfare exo suit.

hy can you make this for me or can you provide the total 10 steps in a tutorial please

Hello, I would like this to be used for people who speak sign language.

dude92 made it!10 months ago

hey man i made it \m/

zootalaws1 year ago

Great project, Bryan.

It does make me laugh, all the 'if you did this' and the knockers - like they ever made a damned thing in their lives.

Keep up the making!

This is awesome! Do you think could be possible to add a bluetooh connection in The glove to use It with your smartphone? It would be fantastic

you could use the glove design to make a glove mouse for your computer

halvi1 year ago

what if we add a touch screen on the hand and monitor the other function. we can simply add. and this will take the fabrication to another level .,,,Say, Glove 2....:D

Is there some way you could save the files as an STL file?

This is so cool! (It's totally Iron Man)

How can u call from that glove u will need a microphone speaker and a sim card with its slot how is this possible
that is so very Tony Stark. Well done

Hi I'm interested on making something like this but JUST the plastic parts. I'm actually building a robotic arm and need a framework to mount sensors on my hand with, that will have raised lengths coming off the top for stretch sensors. A bit like the image below, but I don't need it to be that complicated. I just need to increase the radius around my finger joints so my sensors will stretch further. I could fabricate something out of a barebones version of your glove probably, but I don't have a 3D printer. Is there any way to buy just the plastic parts for a glove from you?

If so please contact me at amadon.faul@hotmail.com

Cool idea! BTW, if you have the watch phone, then it's already a "wearable cell phone!"

This is freaking awesome! I love all your ideas! Will you be my best friend?

You could also pinch the earbud wire between two pieces of fine sandpaper to remove that coating and keep your soldering iron and nostrils clean.

the CAD files wont open on sketch up is there something I am doing wrong
stoptime11 year ago
and incase anyone didn't know most of the burg watches have digital screens now
stoptime11 year ago
is there a way to keep the screen from the watch so you can save contacts incase you can't remember a phones number

Would it be possible to purhcase one from you made to order? I wouldnt mind buying yours if possible. Feel free to call or text me Steve (561) 288-0774 or Steve@fancybeasts.com

wouldn't you need a locking mechanism for the number buttons. say if you were to pick something up you wouldn't want to "hand dial."

im in love with you right now

Don't get me wrong, this is a fantastic design and very cool...especially for people who are into that kind of design.

however, don't you think that as an everyday person usage item...it's kinda going backwards?...

we have micro-technology resulting in Blutooth and it's lightweight, and user friendly. I mean, i believe it would be kind of uncomfortable to walk around with your hand stuck to your head like that.

although it would possibly cut down on driving while talking/texting.

Thanks for the feedback. I highly suggest watching the intro video for this project, to get a better understanding of my motivation behind this project and why I designed it the way I did.

You might also take a look at the project page on my website, here:

Lastly, I highly encourage you to attempt your own build, and share it here on instructables! Don't stop at telling us how you'd improve the design, show us! :)

How much did the watch cost?

A more detailed bill of materials (with prices) can be found on my blog, here:

Thank you
an awesome touch of a genius

Can you make a printable template of a cardboard glove one? thanks

Must be what Tony Stark feels, following you from now on :D Nice work

Have you considered adding a button that disables all other buttons temporarily? That way, you could use the hand for other things without worrying about the next generation of butt-dialing.
